Answer:
Yes, but only if it's sunny.
Explanation:
As you know, solar panels generate energy through the sun's rays of light (better known as sunlight). Therefore, as long as the sun is shining high in the sky, the car will generate electricity and be able to function. If this vehicle was only powered by solar panels, it would not function during the night, in cloudy areas, and/or in dark places (such as parking garages or home garages).
Hope this helps!
Answer:
271cm^2
Explanation:
volume 1= 15^3 =3375
temp. 1. = 20+273 = 293
temp. 2. = 50+273 = 353
volume 2 =?
According to Charles law
volume is proportional to temperature
v2 = v1 * t2 / t1
v2 = 3375 * 353 / 293
v2 = 4066cm^3
v = area * length
4066 = area * 15
area = 4066/15 = 271cm^2
They emit low leavls of carbon dioxide (CO2) and the emissions of green house gases and therefore the contribution of nuclear power plants to global warming is therefore pretty little
Answer:
B) Tommy had a positive acceleration between noon and 12:30 pm.
Explanation:
Acceleration is defined as the rate of change of velocity:
where
v is the final velocity
u is the initial velocity
t is the time
In the problem,
- At noon, Tommy is walking at a velocity of 4 mi/h
- At 12.30 pm, Tommy is walking at a velocity of 6 mi/h
- A time of half an hour (0.5 h) passed between the two moments
So Tommy's acceleration is
and the acceleration is positive, since the velocity has increased.
